For anyone interested, I spent all day poring over multiple sites and videos to get this working.
Parts:
4 in with touch == https://www.aliexpress.us/item/2251832829271342.html?spm=a2g0o.order_detail.order_detail_item.7.1fbbf19cSGM7m6&gatewayAdapt=glo2usa
esp32 == https://www.aliexpress.us/item/2251832696801305.html?spm=a2g0o.order_list.order_list_main.23.2bf81802a56ykm&gatewayAdapt=glo2usa
I followed this wiring diagram
I made the changes for IRQ to GPIO2 and I unplugged the display (MISO) so I just have T_D0 to 19(MISO)
